Serial no .'a9 5,1s8."

In certain types of pneumatic tools, it is the advantageous custom to utilize exhaust ports that open rearwardly from the barrel. Where these tools are handheld and directed, the result is that the exhaust is delivered toward the handle and toward the operator. This is objectionable.

The object of the present invention is to provide a novel, simple and effective means for deflecting the exhaust away from the operator. V

In the accompanying drawings:

Figure 1 is a side elevation of an embodiment of the invention in place on a tool.

Figure 2 is a cross sectional view on an enlarged scale and taken on the line 22 of Figure 1.

Figire 3 is a longitudinal sectional view on the line 3-3 of Figure 2.

Figure 4 is a plan view of the deflector hood blank. 7

In the embodiment disclosed the tool consists of the usual barrel 5 having a rear head 6 secured-to the rear end of the'barrel by side bolts 7. The rear head is provided with a handle 8. It is believed to be unnecessary to disclose and describe the toolas the struc ture is well-known and may be altered in various ways. It is thought suflicient to show the exhaust ports 9 and 10 opening through the rear portion of the barrel, the ports 9 facing rearwardly and therefore directing, the exhaust toward the handle 8 of the tool.

To deflect the exhaust a hood is employed preferably formed of sheet metal, and comprising a body 11 having side walls 12 and connected at its rear end to an anchoring ring 13 by a forwardly tapering neck 14. The ring 13, as illustrated in Figures 1 and 2 is placed between the rear end of the barrel 5 and the head 6 and is clamped thereby to more securely hold it in place. The ring is provided with ears 15 through which the side bolts pass. The side walls 12, as shown in Figures 1 and 2, are bent inwardly and arranged in rearwardly divergent relation with their rear ends abutting the edges of the neck portion 14 and secured thereto by any suit-' able means, as spot welding. The side walls opposite sides of the exhaust 'ports9'-'1O and are'secured thereto by suitable means, as for example, spot welding,;indicated at l6.-

With this structure, it will'be exident that a hood is provided which overlies the exhaust ports and is forwardly flaredso that the airor other fluid discharging from the ports, is deflected forwardly and away from the operator.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim, is:

1. In a fluid operated tool, the combina tion with a barrel having an exhaust port, of a rear head for the ba rrel. and an exhaust deflecting hood covering the exhaust port and having an anchoring ring interposed between the barrel and head and clamped thereby.

2. In a fluid operated tool,

tion with a barrel having an exhaust port, of an exhaust deflecting hood covering the the combination with a barrel having an exhaust port,

exhaust port and having a rear end'secured to the tool, and side walls abutting and secured to the barrel on opposite sides of the exhaustport.

4. In a fluid operated tool. the combination with a barrel having an exhaust port, of a rear head for the barrel, tie bolts se- V curing the head and barrel together, and an exhaust deflecting hood covering the exhaust port and having a ring interposed between the barrel and head and having ears through which the tie bolts pass, said hood having inturned side walls on opposite sides of the exhaust port and abutting the barrel.

5. In a fluid operated tool, the combination with a barrel having an exhaust port, of a rear head for the barrel, tie bolts securing the head and barrel together, and. an exhaust deflecting hood covering the exhaust ort and havin an anchorin ortion through which the tie bolts pass.

3 6. In a fluidoperated tool, the combination with a barrel having an exhaustort, of an element secured to the barrel, t e olts securing the element and barrel together,

and an exhaust deflecting hood covering the exhaust port and havlng an anchorlng por-i tion. through which the tie bolts pass.

In. testimony whereof, I afiix my signature.
